On the drawing:

In the illustrated embodiment of this in- I vention, there is shown acasing formed of a 0 top portion 1 and a bottom portion 2 which are heldtogether'in operative relation by bolts 3 and 4. The top and bottomportions of this casing are'formed with depressions 5 and 6respectively, which are in confronting relationship and form an enlargedsection in the container for receiving the marginal portions of anenergizing coil 7 The energizing coil is disposedaround one leg of aU-shaped core 8 and held against a 17 of the screw head bearing againstthe spring 14. It is therefore obvious that by tightening or looseningthe screw 15 the pressure on thespring 14 may be varied to regulate thevibration of'the armature 1.3.

A pole piece 18 is secured to the armature in position to be influencedby the magnetizing forces set up in the core 8 when the coil 7 isenergized. The free end of the armature 13 is bent at anangleto form aportion 19'which projects through an aperture 20 of the casing 2 andcarries at its outer end a rubber tip 21 which serves as a cuticle setorpusher, when the .arm 13 is vibrated. A rubber stopmember 22 which ispositioned near the free end of the armature 13, serves to cushion saidarmature when moved, outwardly bythe spring-14, and also prevents itfrom striking the casing'2.

- Adouble-pawl ratchet mechanism is. provided fortransforming thevibratory motion of 'the'armature 13 into'a rotary motion, stub shaft 23is-secured to an upwardlyoflset portion 24 at one end of. the plate 9,and projects outwardly through an aperture 25 in the top portionl of thecasing. tubular sleeve 26 havingla ratchet wheel 27 secured to oneendthereof is. rotatably mounted upon the stub shaft .23, the ratchet wheelbeing positioned adjacent the inner end of said shaft and the outer endof. the sleeve projecting to the outside of the casing. The sleeve I 26'isprovided with apair of parallel apertures f28 which' penetrate theinner wall of the sleeve and communicate with a'circumfer'ential groove29 formed in the stub shaft 23. -A U-shaped pin having each leg thereofdisposed in one of said apertures prevents the removal of the ratchetwheel'and sleeve fromthe: stub shaft, but permits the same to rotatefreely thereon. Intermittent rotary motion is imparted to the ratchetwheel 27 by'mean's of a pair ofpawls 30 and 31 which are .pivotallymounted between the arms of "a yoke member 32 carried by the armature13,

saidpawls being secured by a U-shaped pin 33 each leg. of which extendsthrough the yoke arm and flange 33 formed at the end 'of'each pawl, Aspring 34 which is also secured to the yoke member is provided'withcurved ends which bear against the pawls 30. and 31 and hold the freeends thereof in engagement with the toothed periphery of the ratchetwheel 27.

The free end of the pawl 30 terminates in a hook 35 which will engagethe toothed periphery of the ratchet wheel and pullthe same in aclockwise direction when the armature 13 moves away from the ratchetwheel.

The pawl 31 is formed so that the free end thereof engages the toothedperiphery of the ratchet wheel 27' and pushes it in a clock' wisedirection when the armature moves toward the ratchet wheel. Since eachpawl is designed so as to slide overthe teeth when the other pawl isfunctioning to advance said ratchet wheel, .it is apparent that, as longas the armature 13 vibrates back and forth, an'intermittent rotarymotionwill be imparted to the ratchet wheel. I

A variety of interchangeable rotary tools is provided for performing thevarious operations required in manicuring. Thesev tools may beprovidedwith filing surfaces, buffing surfaces, and the like asrequired; means being provided for quickly and easily attach ing anydesired tool." To illustrate the con struction and means for attachingthe tools,

a rotary file 36-is shown; The file 36 comprises ;'a disc portion 3'?having cutting grooves 1n the outer surface thereof, and

terminating'in a circumferential flange 38 which-is similarly'groovedupon its outer surface, The central portion of the disc ter-Inmates in a sleeve 39. which fits coaxially over the sleeve 26 and isheld against 'longi- .tudinal movement by an inwardly project- 1ng n1b40. which engages a circumferential groove 41 in the sleeve 26 Thesleeve 39 is also vprovided with a longitudinally extending slot 41 atone end for receiving a pin 42 carried by the'ratchet wheel 27, therebycausing, the sleeve 39 and ratchet wheel to rotate as a unit. The rotarytool is prevented accidentally disengaged from thefsleeve 26 by means ofa guard plate 42 which is pivotally .secured by a from becoming screw 43to the casing 1'. This guard plate is provlded with a depression 44 forreceiving the end offlthe stub shaft'23, thereby latchmg the guardi'n'position over the rotary tool. The free end ofthe' guard plate 42projects past the edge of the rotary tool and terminates 1n a curvededge 45, which serves as an upper finger rest. A lower nail rest isformed by a lug 46 on the top portion 1 of the casing, said lug beingpositioned on the opposite side of the'rotary tool from the upper fingerrest. When it is desired to remove a rotary tool from the device, theguard 42 is swung to the position shown in dotted lines in Figure'1. 1

The casingis narrowed at one end so that the rotary tool 36 willoverhang the edge 47 the casing thereby in no way interfering with theapplication of the rotary tool in the manicuring operation.

A make and break device comprising an arm 48 and an arm 49 is secured toone of the lateral projections ll by means of a screw 50 whichthreadedly engages a platesuitably 51. Separating blocks 52 areplaced'for insulating the arms 48 and '49.

The'arm 48 carries a contact point 53 and r thearm 49 a contact point54, said points rection, the pawl sliding over the teeth of norm-allybeing in *"engagement.. The arma-' ture;13 carries a, pair. of's'pacedarms of insulating material which 1' are disposed onv either. sidej'oftheprojecting end of the armv '49 of the make and break deviceto-open or providedwithythree'prongs A, B, and C which are formed so asto make contact with mating members in the insertable plug. When thetwo-point plug is disposed in the socket 56 so as to make contact withthe prongs A and Qelectrical connection is established directly to thecoil 7 7 through conductors'58 and This connection should only beused'when operating the device from an alternating current supply.

When it is desiredto operate the device from adirect current'su-pply,the plug is inserted in the socket 56 so as to make contactwith theprongs A and B, which establishes one connection directly to the coil 7through conductor 59. The other side of the circuit whereupon the coil 7is alternately energized and deenergized. When the coil is energized,the armature 13 will be attracted and moved downwardly against thepressure of the spring 14. This downward motion of the .rarmature 13will cause the pawl 31 to advance the ratchet wheel 27 in a clockwisedithe ratchet wheel. Upon the deenergizing of coil 7, the spring 1% willcause-the armature 13 to move in the opposite direction. This movementwill cause the pawl 30 to advance the sprocket wheel 27 in a clockwisedirection, and at the same time the pawl 31 will slide overthe teeth ofthe sprocket wheel and assume a position for its next operation inadvancing the sprocket wheel as before. So long as the armature 13continues to vibrate, the sprocket wheel will rotate and drive therotary tool connected thereto. The cuticle pusher 21 may also be used tostop the rotation of the rotary tool. Since the cuticle pusher is indirect connection with the armature 13, it is evident that theadvancement of the ratchet wheel may be prevented by the V operator ofthe device pushing against the cuticle pusher so that the armature willnot be able to vibrate. This is an advantage in that the operation ofthe rotary tool may be temporarily stopped without electricallydisconnecting the device.

The operation of the device from a direct current supply will be thesame as when operating from an alternating current source, except thatthe plug is inserted in the socket so as to make connection with theprongs A and C. This connection inserts the make and break device in oneside of the circuit to the coil, so that, when the coil is energized,the

armature 13 will be attracted as before and move against the resistanceof the spring 14.

This movement of the armature will cause the to the coil, which nowbecomes deencrgized.

The coil being deenergized, the armature will be moved upwardly by thespring 14, contact 54 will engage contact 53 and reestablish the circuitthrough the coil, which being again energized will attract the armature13 as before. This operation will continue so long as direct current issupplied to the device, or until the device is stopped by the operatorspressing upon the cuticle set 21-. The operation of the ratchetmechanism will be the same as whenoperating from an alternating current.

This invention, therefore, provides a power manicuring device which iscompact in construction, easy to use, which may be operated either fromdirect or alternating current, and which uses a rotary tool, said toolbeing easily and quickly detached from the device for replacing with atool for performing some other operation incident to manicuring.
